Geothermal energy comes from heat stored underground. It can provide both steady, reliable power generation and abundant direct heat for multiple uses.
Geothermal power generation works by using the high-temperature heat under the earth’s surface to produce steam, which then drives turbines to generate electricity. This key renewable source provides over one-fifth of electricity in El Salvador, Kenya and the Philippines. More than 90% of homes in Iceland rely on direct geothermal heat. To promote wider geothermal energy development, IRENA has co-ordinated the formation of the Global Geothermal Alliance (GGA) – a platform for enhanced dialogue and knowledge sharing for coordinated action to increase the share of installed geothermal electricity and heat generation worldwide.
